So ... what other folks said, for sure, but, two points.

1) each project community does this kind of thing largely independently

2) I encourage you to get involved with the communities themselves, and
make this happen. If you feel strongly about it, go make better hashes
for the project(s) you care about. Show us how it's done. Lead by
example, and the projects will pick up your example and do it. I presume
that mechanically it's a very simple step to add to our release
processes, right?
